Glued-in rods for timber structures - An experimental study of softening behaviour

Serrano, Erik LU (2001) In Materials and Structures 34(4). p.228-234
Abstract
A test method to obtain the strength and the fracture characteristics of the bond of glued-in rods for timber structures is presented. Test results from a series of tests using the proposed method are also given. The test method makes it possible to record the complete stress-displacement response of small test specimens. This response includes the softening behaviour after peak stress,i.e. the decreasing stress at increasing deformation. The test series include three adhesives, two rod-materials, four load-to-grain angles and two timber qualities with different densities. A method to evaluate the fracture-softening behaviour is also proposed. The fracture softening is evaluated by using only a part of the stress-displacement curve. The... (More)
